Evolution of Intramedullary Screw
Intramedullary screws are type of implant designed to sit within the bone being fixated. Benefits of intramedullary fixation include little to no hardware prominence, ease of implantation, and the allowance of micromotion about a fracture site to provide stronger bony healing.
Intramedullary screws can be fully-threaded, partially-threaded or variably-threaded, depending on fixation strategy utilized. They are often cannulated, which allows for insertion over a guidewire. Where strength is of a concern, solid implants can also be used, which provide a much stiffer ultimate fixation construct.
The Mitek GII Anchor (QUICKANCHOR)™ is an interference fit anchor designed to provide quick insertion and excellent pullout strength. It comes preloaded with Orthocord, Panacryl or Ethibond sutures, each which provide a unique blend of flexibility and tensile strength. The small drill hole avoids over-resection of bone, which could lead to articular surface penetration. The titanium allow is strong and closely matches the material characteristics of bone to ensure optimal biocompatibility
